為什麼我們在打雷之前會看到閃電？

Now, very soon, you are going to hear some thunder.

現在，很快，你們就會聽到雷聲了。

Do you know why you saw the lightning before you heard the thunder?

你知道為什麼在聽到雷聲之前就看到了閃電嗎？

An interesting fact is that lightning and thunder occur at the exact same time.

一個有趣的事實是，閃電和雷聲是同時發生的。

This is because light travels faster than sound.

這是因為光的傳播速度比聲音快。

The speed of light is 300 millimeters per second.

While the speed of sound is only 340 meters per second.

Thus, the light from the lightning travels much faster to our eyes.

是以，閃電的光線到達我們眼睛的速度要快得多。

As a result, we first see the lightning, shortly followed by the sound of thunder.

是以，我們首先看到的是閃電，然後是雷聲。
